The human body is a living machine, and, like all machines, it needs "fuel" to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy? The energy value of food is usually measured in calories . A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1degC. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on. The energy in food is in the form of three kinds of chemical materials--carbohydrate , protein  and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show. (P= protein      C= carbohydrate    F=fat) Which of the following contains the most amount of calories? A) Milk. B) Rice C) Peanuts. D) Milk or peanuts.

(Q).
Harry is a boy with a learning disability. On his fourth birthday, he was given a pug called Millie. Two weeks after the dog's arrival, he was happier and calmer and said his first words, "dog" and "mummy". Just two months later, thieves stole the dog, and now the heartbroken little boy is back to where he started. He has refused to talk since losing his best friend. His mother was worried and gave him another dog, but he just "pushed it away". Mrs Hainsworth, his mother, says, "My son is very sad. He'll go over to her cage and just beat  on the bars. There is no word coming out, but you just know he's screaming 'Where is Millie' inside. Millie was really his best friend. They would play together happily for hours. None of his toys has ever held his attention that long. Now he has just completely turned quiet again. "Harry suffers from a condition which affects his ability to speak and move. But the dog's being with him achieved more in days than months of speech therapy and physiotherapy had. Mrs Hainsworth says, "My son was so happy when he saw Millie. Being with Millie changed him, and within two weeks he had said his first words and was working on saying 'dad'. Just last week, his teachers and I were saying how much Millie had helped him. And now this!" Mrs Hainsworth is considering buying another pug in the hope that her son will accept it. Maureen Hennis of the charity, Pets as Therapy, says she has seen many cases of dogs helping people with speech problems. "People may talk to a dog when they wouldn't like to talk to another human," she says. "A dog doesn't care if words come out wrong." Before getting Millie, Harry . A) had never seen a dog B) had never said a word C) had received little treatment D) had never played with toys

(Q).
Ask any student which subject he or she hates most. 9 out of 10 students will answer "math". No matter which country you visit, no matter which grade you are in, you may not learn art, geography, chemistry or Chinese, but you always learn math. Why is this so? How come so many students hate math, and yet cannot avoid learning it in school? Jenny Sanders, a high school student in California, asks, "What good do we get from learning math? We can use computers to compute numbers, and we can use computers to store information. I think learning math at school is a waste of time." However, there is much more to math than just learning to add and subtract   numbers. In fact, math is not so much about calculation   as it is about learning to think logically   and solving problems. Of course, Jenny was right that we can use computers to do calculations, but how would we even know how to use the computer if we can't think logically? In short, computers are only tools when solving problems. For example, imagine you are a cook and must serve dinner to 100 guests. How should you divide your resources so that you can get the job done most efficiently  ? In situations like this, the ability to think logically will get you to a reasonable answer and solve your problem. According to the passage, which subject do students always learn in different grades at school? A) Chinese B) Math C) Geography D) Art.
